Description

Grip for Golf Club and Golf Club Equipped with the Same}

The present invention relates to a grip of a golf club. More specifically, a second protrusion that protrudes more than the first protrusion is formed on the inner circumferential surface of the grip of the golf club, so that when the shaft is fitted to the grip, the outer circumferential surface of the grip protrudes outwardly by the second protrusion so that the golf club is stable. It is about the grip of a golf club that can be gripped with.

As shown in Figure 1, the grip of a typical golf club has a circular or oval cross section, and the upper and lower diameters of the grip are almost the same or slightly tapered, so that it is difficult to hold a stable grip, so as to use an accurate shot. There is a difficulty, and there is a problem that the club is returned from the hand during the slip and wrong impact due to the centrifugal force during the swing of the golf club.

In addition, there is a conventional technique to prevent the slip of the hand by the centrifugal force by making a non-slip groove in the left hand little finger part, but in this case, a considerable portion of the centrifugal force is concentrated in the left hand little finger part, so that the friction force cannot be distributed on the entire surface of the palm of the hand. Posture of the hand after the swing, that is, there is a problem that the adhesion of the hand and the grip is disturbed.

The present applicant has filed a patent application No. 10-2004-0077476 for the grip of the golf club, characterized in that the diameter of the upper part of the grip is formed larger than the lower part of the grip, the cross section of the upper part of the grip is formed in an elliptical shape.

By the way, since the grip of the golf club according to the invention of Patent Application No. 10-2004-0077476 is produced so that the protrusion is formed on the outer circumferential surface from the beginning, a slight distortion occurs when the ball hits the grip after grip, in particular, such a distortion phenomenon Has a problem that becomes worse in the case of miss shot. In addition, after injection molding of the grip, sanding work is required to remove the debris formed on the outer peripheral surface of the grip and to grip the outer surface of the grip. There is a problem that is difficult to make.

Meanwhile, as shown in FIGS. 2A and 2B, a protrusion 201 having a predetermined distance in the longitudinal direction of the grip is formed on the inner circumferential surface of the grip, and pressure is applied to the protrusion 201 while the shaft is inserted into the grip. When applied, the outer circumferential surface of the grip protrudes outward so that the club comes into close contact with the hand when swinging.

However, the grip of the golf club according to the prior art has a small protrusion of the outer circumferential surface even after the engagement of the shaft because the protrusion 201 protrudes to about 1 mm into the inside of the grip, so that the club is in close contact with the hand.

The present invention is designed to solve the above problems, to ensure that the grip of the golf club can be held reliably to realize accurate shots and long flying distance, so that the centrifugal force is distributed throughout the palm when swinging, so that even after the swing The main purpose is to help the golfer improve his skills by preventing his posture.

In addition, the present invention has a main purpose to ensure that the golfer grips the grip of the golf club so that the distortion does not occur when the impact, and the standardization of the protrusion of the protrusion when the grip is produced.

In order to achieve the above object, the present invention, in the grip of the golf club, the inner circumferential surface of the grip toward the inner side of the grip is formed with a predetermined distance in the longitudinal direction of the grip, the shaft of the grip A first protrusion, which is inserted into the inner side, receives a pressure in the direction of the outer circumferential surface of the grip by the shaft, and protrudes the outer circumferential surface of the grip outwardly; And a predetermined distance in the length direction of the grip on the upper side of the first protrusion, the protrusion protrudes more than the first protrusion, and the width is wider than the width of the first protrusion, and the shaft of the grip When inserted into the inner side is provided by the shaft in the direction of the outer circumferential surface of the grip provides a grip of the golf club, characterized in that it comprises a second projection protruding outwardly the outer circumferential surface of the grip.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. First of all, in adding reference numerals to the components of each drawing, it should be noted that the same reference numerals are used as much as possible even if displayed on different drawings. In addition, in describing the present invention, when it is determined that the detailed description of the related known configuration or function may obscure the subject matter of the present invention, the detailed description thereof will be omitted.

3 is a longitudinal cross-sectional view illustrating a grip of a golf club according to an embodiment of the present invention, FIG. 4 is a cross-sectional view taken along the line AA ′ of FIG. 3, and FIG. 5 is a cross-sectional view taken along the line B ′ B ′ of FIG. 3.

3 to 5, the grip of the golf club according to the embodiment of the present invention, the first protrusion 301 is formed with a predetermined distance in the longitudinal direction of the grip on one side of the inner peripheral surface 305 of the grip ), The first inclined portion 307 extending from the lower side of the inner circumferential surface 305 of the grip to the upper side of the inner circumferential surface 305, the shaft contact portion 306 extending from the first inclined portion 307, and the shaft contact portion 306. The second inclined portion 309 which extends from the inner circumferential surface 305 so as to meet the upper side of the inner circumferential surface 305, and the left inclined portion 501 and the right inclined portion 503 extending from the inner circumferential surface 305 of the grip toward the center of the grip. And a second protrusion 303 having a predetermined distance in the longitudinal direction of the grip and having a width greater than that of the first protrusion 301.

The first protrusion 301 is formed to have a predetermined distance in the longitudinal direction of the grip on one side of the inner circumferential surface 305 of the grip, it is formed to protrude slightly into the inside of the grip. Although described as protruding here, it is to be understood that the inner cross section of the grip is substantially circular so that the first protrusion 301 has flattened a portion of the lower part of the circular cross section. Accordingly, when the shaft is inserted into the grip, the shaft exerts a pressure on the first protrusion 301, thereby causing the outer circumferential surface of the grip to protrude outward.

The second protrusion 303 includes a first inclined portion 307, a shaft contact portion 306, a second inclined portion 309, a left inclined portion 501, and a right inclined portion 503.

The first inclined portion 307 is a portion where the upper side of the shaft contacts when the shaft is engaged, and the second protrusion 303 ruptures as the second protrusion 303 is pushed upward by the upper end of the shaft. The shaft is formed obliquely toward the upper side of the grip to prevent the wear or wear and smoothly engage the inner peripheral surface 305 of the grip. In addition, the first inclined portion 307 may be formed to form an angle of 35 degrees to 43 degrees with the inner circumferential surface 305 in an upward direction of the inner circumferential surface 305, and preferably may be formed to form an angle of 38 to 41 degrees. have.

In addition, a portion where the lower end of the first inclined portion 307 and the inner circumferential surface 305 meet is subjected to a tensile force to be pulled upward by the upper side of the grip when the shaft is inserted. In order to prevent the portion where the lower end of the 307 and the inner circumferential surface 305 meet from being ruptured, a portion where the lower end of the first inclined portion 307 and the inner circumferential surface 305 meet is preferably a smooth curved surface.

The shaft contact portion 306 is a portion in which the second protrusion 303 and the outer circumferential surface of the shaft are in contact with each other when the shaft is coupled to the grip, and at the same time, the portion is pressurized so that the second protrusion 303 is pushed out of the grip by the shaft. . The shaft is preferably in close contact with the shaft contact 306 in order to be stably fixed to the inner circumferential surface 305 of the grip after the shaft is fully engaged with the grip. Therefore, the surface of the shaft contact portion 306 may be concave in the inward direction of the second protrusion 303 to be in close contact with the outer circumferential surface of the shaft, but is not limited thereto.

The second inclined portion 309 is a portion in which the shaft contact portion 306 extends to meet the upper side of the inner circumferential surface 305 of the grip, and the shaft pushes the second protrusion 303 upward of the grip when the shaft starts to engage. In order to prevent the point where the second protrusion 303 and the inner circumferential surface 305 of the grip meet from being ruptured, it is formed obliquely toward the upper side of the inner circumferential surface 305 of the grip. In addition, when the second inclined portion 309 does not exist and the shaft contact portion 306 extends as it is to directly meet the upper inner circumferential surface of the grip, a problem arises in that the upper outer circumferential surface of the grip is crushed after the shaft is engaged. The present invention can prevent the occurrence of such a problem.

More preferably, the point where the upper end of the second inclined portion 309 and the inner circumferential surface 305 of the grip meet may be treated as a curved surface, but is not limited thereto. In addition, the second inclined portion 309 may be formed to form an angle of 35 degrees to 43 degrees with the inner circumferential surface 305 in the lower direction of the inner circumferential surface 305, and preferably may be formed to form an angle of 38 to 41 degrees. have.

The left inclined portion 501 and the right inclined portion 503 are portions in which the inner circumferential surface 305 of the grip extends in the radial direction of the grip to constitute the side surface of the second protrusion 303. The left inclined portion 501 and the right inclined portion 503 are formed obliquely in the radial direction of the grip to prevent the second protrusion 303 from being deflected to the left or right side of the grip while the shaft is engaged. In addition, when the shaft is engaged, the second protrusion 303 is pushed to the left and right, and the point where the left inclined portion 501 and the right inclined portion 503 and the inner circumferential surface 305 of the grip meets is not broken. It is preferable to process the curved surface, but is not limited thereto.

On the other hand, the inner side of the second protrusion 303 to form a core (Core) made of the same or different material as the other parts of the grip so that the shaft contact portion 306 of the second protrusion 303 after the coupling of the shaft than the shaft You can also try to get a better fit. The core may be formed of an object made of a hard material such as plastic or metal, but is not limited thereto.

In addition, when the second protrusion 303 protrudes too much into the inside of the grip, there is a problem that a considerable amount of effort is required when engaging the shaft, while the shaft is gripped when the second protrusion 303 is slightly protruded. Even if coupled to the outer peripheral surface there is a problem that there is little effect of protruding. This problem also applies to the case where the length of the second protrusion 303 is too long or too short.

Accordingly, the second protrusion 303 is formed to have a length of 50 to 95 mm, preferably 60 to 75 mm, in the longitudinal direction of the grip, and 3 to 5 mm, preferably in the radial direction of the grip from the inner circumferential surface 305. It is preferably formed to protrude about 4.3 to 4.7 mm.

A case in which a shaft is coupled to a grip of a golf club according to an embodiment of the present invention having such a configuration will be described in more detail with reference to FIGS. 6 and 7.

As shown in FIGS. 6 and 7, when the shaft 601 is coupled to the grip of the golf club according to the embodiment of the present invention, the shaft 601 pushes the first protrusion and the second protrusion toward the outside of the grip. Thus, the outer peripheral surface 603 of the grip is protruded outward. In addition, gaps that may occur between the shaft and the inner circumferential surface of the grip are filled with adhesive.

When the outer peripheral surface 603 of the grip protrudes, the diameter of the upper part of the grip is larger than the diameter of the lower part of the grip, so that the upper part of the grip can be securely gripped with the left hand and the lower part of the grip with the right hand is excessively gripped with the right hand. You can prevent the force from entering.

In addition, it is possible to prevent the left hand sliding due to the centrifugal force during the swing by the stop engaging portion 605 formed by the outer circumferential surface 603 protruding. Most of the centrifugal force generated during the swing acts on the left hand, and since a considerable amount of the force acting on the hand acts on the grip force by the left hand ring finger and the middle finger, when the stop engaging portion 605 is formed in the left hand grip part, the left hand acts on the left hand. A significant amount of centrifugal force acts on the stopping portion 605 and the other finger is subjected to a tensile force. Therefore, due to the formation of the stopping portion 605, the force is distributed as a whole, so that the sliding of the left hand can be effectively prevented. However, the position of the stop engaging portion 605 may be located between the left hand index finger and the middle finger when holding the grip, but may be located between the middle finger and the ring finger, between the ring finger and the little finger. In addition, since the stop portion 605 is formed as the shaft 601 pushes the second protrusion to the outside of the grip, the position of the stop portion 605 depends on the position at which the second protrusion is formed.

In addition, even if the shaft 601 pushes the second protrusion to protrude the outer circumferential surface 603 of the grip, a tension is applied between the other parts to pull the protruding portion tautly, so that the golfer makes a hand even when the golfer makes an impact. The warping phenomenon such as slipping in the wind will be reduced.

On the other hand, the grip of the golf club is produced by injection molding using an elastic material such as rubber, the rubber is formed on the surface of the protrusions when the injection molding is to be formed on the outer peripheral surface side of the grip from the beginning. Therefore, a sanding operation is required to remove such rubber debris. As described above, since the sanding operation is performed by hand, the degree of protrusion of the protrusion is changed according to the strength or skill of the operator. That is, uniformity is not achieved.

However, according to the present invention, since the grip is injection-molded so that the first protrusion and the second protrusion are formed on the inner circumferential surface of the grip, the grip has an outer circumferential surface of a certain ratio and the uniformity or standardization can be achieved during the sanding operation for removing the rubber residue. .

The matters described in this specification in relation to the present invention are all described based on the right-handed golf club, but the technical concept of the present invention is applied to the left-handed golf club as it is.

The above description is merely illustrative of the present invention, and those skilled in the art to which the present invention pertains may make various modifications and variations without departing from the essential characteristics of the present invention. Therefore, the embodiments disclosed in the present specification are not intended to limit the present invention but to describe the present invention, and the scope of the technical idea of the present invention is not limited by these embodiments. The scope of protection of the present invention should be interpreted by the following claims, and all technical ideas within the scope equivalent thereto shall be construed as being included in the scope of the present invention.

As described above, according to the present invention, the grip of the golf club can be stably held to realize accurate shots and long flying distances, and the centrifugal force is distributed to the entire palm when swinging so that the posture of the hand is maintained even after the swing. It is effective to help golfers improve their skills by not disturbing them.

In addition, according to the present invention, there is an effect of preventing the sliding of the left hand (or right hand) due to the centrifugal force during the swing by the stop engaging portion formed by the outer peripheral surface protruding.

In addition, according to the present invention, even when the shaft pushes the second protrusion and the outer peripheral surface of the grip protrudes, tension is applied between the other parts to pull the protruding part tightly, so that the club is held in the hand even when the golfer makes an impact. There is an effect that the distortion, such as slipping is reduced.

In addition, according to the present invention, since it is not necessary to form a protrusion on the outer peripheral surface there is an effect to enable uniformity or standardization of the production of the product during the sanding operation.
